Abstract

A fire extinguishing system valve (1), in particular wet alarm valve, dry alarm valve or spray water valve, having a housing (3) which has a fluid inlet chamber (9), a fluid outlet chamber (11) and a closing body (13) which can move back and forth between a blocking state and a release state, wherein the fluid inlet chamber (9) and the fluid outlet chamber (11) communicate directly with one another in a fluid-conducting manner in the release state, and the closing body (13) prevents the direct communication between the fluid inlet chamber (9) and the fluid outlet chamber (11) in the blocking state. The housing (3) has a dedicated discharge duct (30) which has at least one inlet (30a, b) connected to the fluid outlet chamber (11) and an outlet (30c) leading out of the housing (3) of the fire extinguishing system valve (1), and which is integrated into the housing (3).
